I did a one-year exchange at GCU and stayed at Caledonian Court. The University itself is made for you to enjoy the experience, as Campus facilities are very comfortable to spend your day there studying, having lunch, doing group projects, etc. Also, the gym is on campus, which is an extra point. Its student body makes sure the experience of international students (enrolled full time but also Erasmus) do make the most of the experience, including languages, career advice, and getting to know the Scottish culture (and Glaswegian nightlife) while getting to know fellow students from different programs.
The only con out of all its pros would be the university’s accommodation, as the price does not live up to the quality of its facilities. However, it is made for student life, so if you’re a first-year student or an exchange student, it’s a great place to make friends and party while next to campus.
